    Description

      In some load testing, I got a TaskTracker into a state where its Jetty server is in a tight loop calling epoll_wait, which is returning EINVAL:

      [pid 19573] epoll_wait(157, 40829000, 8192, 0) = -1 EINVAL (Invalid argument)

      It's not responding to any HTTP connections - connections are accepted and then just hang.
